QTL effects on the three production traits in oil palm. a Correlation between production variables at QTL positions, measured as the Pearson correlation coefficient between BLUPs of the random QTL effects for each variable pair. The color scale indicates the strength of the correlation, with green and red being perfect positive and negative correlations, respectively. b Relationships between QTL effects for bunch number (BN) and average bunch weight (ABW) in heterotic group B parents are presented using the convex hull encompassing the scatter plot of parental BLUP values (n = 146). Convex hulls are drawn for BLUPs at three QTL positions on linkage group 1 (B_1@159), 15 (B_15@117) and 16 (B_16@57)
